Rob Clark d7be05aff2 dma-debug: make things less spammy under memory pressure ... [ Upstream commit e19f8fa6ce1ca9b8b934ba7d2e8f34c95abc6e60 ] Limit the error msg to avoid flooding the console. If you have a lot of threads hitting this at once, they could have already gotten passed the dma_debug_disabled() check before they get to the point of allocation failure, resulting in quite a lot of this error message spamming the log. Use pr_err_once() to limit that.
